1993 I5 2.5 TD

I'm looking at a '92 300D with 270k miles on it. It looks to be in good condition and well cared for. I have heard that at this mileage the compression can be low, making it difficult or impossible to start in colder weather. If this is the case with this particular vehicle, can this be determined by visual inspection? Or how can I check for compression issues? What else should I look out for? Any help would be appreciated.

It is not too difficult to do compression test on this 5 cylinders.
Even in extremely expensive CA it can be done for about $200.
Than cold starting issue might have nothing to do with engine wear out. 270k is about 1/4 of engine life, so it is not much.
In very cold temperatures diesel need to have block heater working for at least 2 hr before start up.

What sort of a maintenance history does the car have (if any)?
